Graco adds more than 403,000 child seats to recall

But the added seats won’t end a dispute with the U.S. government’s road safety watchdog. The National Highway Traffic Safety Administration still wants Graco to add 1.8 million infant seats to the recall because they have the same buckles.

Buckles can get gummed up by food and drinks, making it difficult to remove children. In some cases parents have had to cut harnesses to get their children out. The agency says the problem increases the injury risk in emergencies.

Graco says in a letter to the agency that it found additional toddler and harnessed booster seats that should be recalled. The company still believes the infant seats should be excluded.
